variation in cord insertion

There can be several variations with cord insertion into the placenta:

  • central insertion (~90%): normal situation
  • eccentric cord insertion: lateral insertion of the umbilical cord >2 cm from the placental margin
  • marginal cord insertion (~7%): insertion of the umbilical cord <2 cm from the placental margin
  • velamentous cord insertion (~1%): insertion of the umbilical cord on the fetal (chorioamniotic) membranes
